Release Notes for Cisco NCS 6000 Series Routers, Release 5.0.0The Cisco Network Convergence System (NCS) 6000 series router delivers outstanding network agility, packet optical convergence, and a system scale measured in petabits per second. It also facilitates the build-out of next-generation core to:Running the Cisco IOS XR operating system, Cisco's innovative virtualized operating environment, the Cisco NCS 6000 series router advances the concept of distributed routing and virtualization. With Cisco Virtualized IOS XR, the Cisco NCS 6000 series router brings new levels of programmability and virtualization to:
The Cisco NCS 6000 series router is engineered for environmental efficiency, with the use of adaptable power consumption. The Cisco NCS 6000 series router is powered by the Cisco nPower Network Processor Units (NPU). These technologies aid the Cisco NCS 6000 series router to achieve the lowest carbon footprint in service provider routing.
The Cisco NCS 6008 router, part of the Cisco NCS 6000 series routers, is the next-generation core routing system that provides industry-leading 8 Tbps of full-duplex network bandwidth through eight line cards.
The Cisco NCS 6008 router runs on Cisco IOS XR software with Linux as the underlying host operating system. A Kernel-based Virtual Machine (KVM) hypervisor provides a virtualized environment to independently run system administration and routing functions on separate virtual machines. This provision makes the new system versatile and robust, and provides immense flexibility for future expansion without the need for a complete system overhaul.
A multi-slice architecture of line cards enables the system to be configured in a mixed operating mode, simultaneously supporting traffic at 10 Gbps and 100 Gbps on slice-level granularity.
These release notes describe the features provided in the Cisco IOS XR Software Release 5.0.0 for the Cisco NCS 6000 series router and are updated as needed.

What's New in Release 5.0.0
Routing and System Administration by Virtual Machines—On the Cisco NCS 6008 system, the routing functions and the system administration functions are run on separate virtual machines (VMs) over a Linux host operating system. The VM simulates a physical computing environment over common hardware. Available hardware resources like processor, memory, hard disk, and so on, are virtualized and allocated to individual virtual machines by the hypervisor.
- Cisco NCS 6008 Router
- The Cisco NCS 6008 Router 8-Slot Line Card Chassis (LCC) is a fully distributed system. All packet-forwarding decisions and actions take place on the individual line cards to provide high-speed, flexible forwarding. The control plane is independently managed by the route processors, which communicate with other network elements, then send the feature and forwarding instructions to the line cards.
- The Cisco NCS 6008 router provides an operationally efficient infrastructure. All common components, route processors, switching fabric, fans, and power supplies are fully redundant. In addition, the platform uses power on an as-needed basis, depending on system requirements. Power has been modularized to reduce capital expenditures (CapEx) and provide operationally efficient deployment. For environment efficiency, each line card’s power consumption is adapted to the number of ports used.
- Integrated technology includes IP and Multiprotocol Label Switching (MPLS) routing, fabric multicast replication, fabric quality of service (QoS), Cisco NetFlow Accounting, and a services implementation infrastructure to provide an outstanding quality of experience (QoE) at the lowest possible total cost of ownership (TCO).
- Cisco NCS 6000 Series 10-Port 100 Gbps Line cardsThe Cisco NCS 6000 series router delivers the highest throughput, while allowing for natural evolution of existing network architectures and for tighter integration between the routing and optical transport networks. To help achieve these performance objectives, Cisco NCS 6000 series router line cards can be deployed in the following ways, based on the capabilities required:Cisco NCS 6008 router supports the following line cards:The Cisco NCS 6000 Series 10-port 100-Gbps Line Cards offer significant advantages:

- Advanced Cisco nPower Layer 3 forwarding NPU with wire-rate lookup, forwarding, and QoS performance for IP and MPLS flows.
- Built-in hardware acceleration for critical network control traffic.
- Support across all Cisco NCS 6000 Series single-chassis and multi-chassis configurations.
- Support for the Cisco AnyPort technology allowing short-reach solutions to mix and match 10 GigabitEthernet and 100 GigabitEthernet interfaces.
- Efficient environmental design by adapting the power consumption to active Cisco nPower resources.
- Independently programmable and upgradable NPUs with fault protection and isolation.
- Enhanced onboard multi-core CPU for accelerated and scalable software processing.
